摘要

采用0.5 pn IBM Si- BiCMOS技术，设计并制作了一款适用于GSM/DCS/PCS三波段直接转换接收机的全集成VCO。该VCO在3MHz偏置时实现了-143 dBclHz的相位噪声，频率为3.4GHz，带宽超过600MHz。讨论了快速开关自动选带电路的设计。VCO的总电流为10 mA，电源为2.8V。

A fully integrated GSM/DCS/PCS Rx VCO with fast switching auto-band selection

A fully integrated VCO suited for GSM/DCS/PCS tri-band direct conversion receiver is designed and fabricated in 0.5 pn IBM Si- BiCMOS technology. The VCO has achieved a phase noise of -143 dBclHz at 3MHz offset with a frequency of 3.4GHz and more than 600MHz bandwidth. The design of the fast switching auto-band selection circuit is also discussed. The total current for VCO is 10 mA with a 2.8V supply.
